To all whom, t may concern:

drum and suitable drivin Be it known that we, EpwAnD H. LANIER and FRANKK. DRIESBACH, citizens of the United States, residing at Cincinnati,Hamilton county, Chio, have invented certain new and useful Improvementsin Pastry Molding and Baking Apparatus, of which the following is aspecification.

The present invention relates to improvements in machines for formingand baking hollow pastry and particularly to machines adapted for bakingthe articles commonly known as ice cream cones.

The object of the invention is to provide a simple but effective machineby means of which large quantities of such articles may be produced in aminimum amount of .time

and without requiring particular attention from an attendant. That is,the object of the inventionis to provide a machine for the purposedescribed which is automatic in its action.

In the accompanying drawings,

Figure 1 is an elevation, and partial section, with some of the partsbroken away, of a machine constructed in accordance with the invention;

Fig. 2 is a sectional view substantially on the line 2--2 of Fig. 1,some of the parts of the mechanism being omitted for the sake ofclearness;

Fig. 3 is a plan view of a part of the mechanism Fig. 4 is a detail viewof one setof the molding devices;

:Referring to the drawings, it will be seen that the-machine comprisesessentially a wheel or drum which is rotatably mounted upon a stationaryaxle 1, and provided with a series of mold cavities or sockets, and anendless carrier provided with a series of mold members corresponding toand adapted to enter the cavities or sockets in said drum, the .carrierbeing supported by the wheels. The axle 1 is mounted in a suita le frameand the drum thereon 'is inclosed throughout the greater'l portion ofits extent by a casing or As shown, the drum comprises a hub 5,.

spokes 6 and a rim 7, the latter projecting on both sides of the spokesand being provided Y with suitable openings to receive the Socket orfemale members of the molding devices. Such members of the moldingdevices are preferably made in the form shown, comprismg two sectionsor'members 8 pivotally connected at their lower ends, as at 9, andhaving at the upper end expanded or projecting plate-like portions 10which extend over the openings in the drum rim 7. Rods 11 connect thetop members 10 of each mold section with lugs 12 at the lower end of thesection,

said rods extending through suitable openings 1n the drum rim andconstituting a means for positively moving the two sections of eachfemale member of a molding device to and from each other as said deviceis adjusted' radially of the drum, as will be hereinafter more fullydescribed. The drum is provided with two sets or'series of moldingsockets, varranged on opposite sides of the spokes 6 and each of saidsockets is connected at its inner end with a rod 13 that extends throughsuitable passages in arms or plates 14,. extending laterally .from thespokes. The connection between eachrod 13 and its associated moldingdevice preferably includes a yoke-like member 15 and said yoke isprovided with a lateral projection'or stud 16 adapted to coperate withstationary guides as the drum rotates to impart longitudinalreciprocating motion to the rods 13 and mold devices connectedtherewith.

The male members of the molding devices are supported by an endlesscarrier-comprising two chains connected. at proper intervals cores 24:being suspended from or attached to said cross bars by heads 19, havingvtherein apertures through which the cross bar extends, and set screws20. The cross bars are of such length that'they vproject laterallybeyond both sides ofthe endless carrier and are-adapted to engage theperipheral notches or teeth vof drive .wheels 21 mounted on a shaft 22adapted to be driven by any suitable power, for example an electricmotor. the 4shaft 22 is rotated so that the endless core supportingcarrier moves in the direction of the arrow, Fig. 1, and means,hereinvafter described, are provided for causing the cores to propertenter the socket members on the drum an rotate the same about theaxle 1. At a suitable point Vstationary inclined guides 23 are provided,said guidesl havinggrooves through which the lugs or studs 16 on thefemale members of the .molding devices are adapted to pass; and the ltoguides 23 are so positioned that in traversing the grooves thereof saidsocket members will be positively moved radially of the drum anddisengaged from the cores 24. Means are provided at points between thedriving shaft 22 and the drum for coating the cores 24 with batter. Asshown, this means comprises a tank or receptacle 25, in which asulicient quantity of batter is constantly maintained when the machineis operating, and a vertically movable dipper 26 adapted to be lowered.into the tank and therein filled with batter or to be elevated aboutcores 24. Preferabl this dipper is provided with four cham ers orpockets each adapted 'to receive one of the cores 24 and a suiicientquantity of batter to form one of the pastry receptacles. Any suitablemeans for reciprocating the dipper 26 may be provided. In the embodimentof the invention illustrated said dipper has upwardly extending sidearms which are connected by a cross rod which is linked, as by a link27, to the longer arm of a lever 28 fulcrumed at 29 on the frame-work ofthe machine. The shorter arm of the lever 28 is-provided with a roller30 that extends into the paths of the set screws 20 by .which the cores24 are securedto the endless carrier. Therefore, as the cores passbeneath the roller 30, the lever 28 will be actuated and the dipper 26reciprocated to supply the proper coating of batter 'to the cores 24which at that time are positioned above the batter receptacle 25.

It will be seen that the parts are so arranged. as to cause the cores 24to Aoccupy a substantially vertical position while passing over thebatter receptacle and, in order to insure that the coated cores willproperly enter the mold'sockets or cavities in the rotary drum, meansare provided for rocking the supporting bars or shafts 17 after thecores have been coated with batter, as described. For this urpose, thereare provided, in the path o each series of screws 20, tilting arms 31which are pivotally mounted on guide shoes 32 and normally held bv theaction of springs 33 inthe path of said screws 20. 'Referring to Fig. 1,it willbe understood that asthe screws 20 contact with the lower ends ofthe members 31 the tension of the spring 33 will be sullicient to causethe core sup orting shaft 17 to rock in its bearings so t at the screwsmay pass beneath the guides 32 and the cores be .positioned at theproper angleV to enter the mold sockets -or cavities on the revolvingdrum. As the core carrier continues to move the tension of the spring 33will be overcome and the member 31 rocked about its pivot so 'that thescrew 20 in contact therewith can pass beyond said member, after whichthe'spring 33 will return the member 31 to its normal, substantiallyvertical, position.

1t is important that the coated cores be forced into the molds to thefull extent and to effect this, there are provided two pressure rollers35 adapted to contact with the enlarged plate-like heads of the cores 24and under the influence of springs 36 insure proper register of themembers of the molding devices.

As the drum revolves the batter between the cores and mold sockets will.be baked and as the lugs 16 pass through the guides 23 the cores andmold sockets will be separated, the latter being withdrawn and the bakedarticles remaining on the cores from which they are subsequently removedas will be described later on. The lrst movement of separation ofthecores and mold sockets, due to the engagement of the lugs 16 and theguides 23, will act to impart a slight movement of the baked article onthe core, owing to the engagement between the fluted or roughenedinterior face of the mold socket and the pastry. This will be suilicientto detach the cone from the base of the core. As the pins or lu s 16travel through the grooves of the gui es 23 and the mold sockets aremoved radially outward the members thereof will be positively separatedso that the baked cone is readily withdrawn from the mold socket on thecore. point between the plane ofthe shaft 22 and vthe point where thecores and mold sockets are thus separated stripping means are rovidedfor positively lifting the cones rom the cores. As shown, this meanscomprises a lever 37 at each side ofthe machine, the forward ends ofsaid levers. bein provided with forks or prongs adapted to lightlyengage the baked articles and at the rear ends said levers are connectedor provided with enlargements adapted to be engaged by the projectingends of the members 17 of the endless core carrier so that said levers37 willbe intermittently rocked to cause the engaged cones to be movedbeyond the points of the cores. The cones thus discharged are receivedona suitable slide or chute from which they are conveyed to one side ofthe machine. In order to close the members of the mold sockets andreturn them to proper position toA receive the coated cores as the drumrevolves, stationary guides 38 are provided being so arranged that thepins 16 in traveling over the inner faces thereof will .be forced radially toward the axis of the drum and therebv bring the mold sockets intoclosed position.

It isbelieved that the operation and adn vantages of the improvedmachine will ybe understood from the foregoing description in connectionwith the drawings and it will b e seen that the invention provides avery simple automatic mechanism by which a rel atively large number ofhollow pastry forms can be pro u'ced and baked with a minimum avm-ant ofattention. @wing to the greater At a suitable grammatically and in someof the views, for example Fig. 2, a number of parts which might be shownare omitted.

If necessary the. mold sockets and cores may be greased. so that thepastry will not tend to unduly adhere thereto. In practice it is notfound necessary to grease the mold sockets frequently but the cores needsuch treatment at frequent intervals.' Grease may be ,applied to thecores by any suitable means, such-as a brush or cloth.
